Overview of CFL Verification Testing Results Jan 2010-Apr 2014 ENERGY STAR Road mapping call on future verification testing of lamps: July 31 st 2014 Taylor Jantz-Sell, EPA

CFL Verification Testing Summary • 424 models tested from Jan 2010-Apr 2014 • Note products could have experienced a marginal failure on one test and a full failure on a another test so they count as full failures

Products failing one or more tests • Marginal failure was defined 80 in CFL 4.0 as one sample 68 70 exceed the allowable failure rate for one test. 60 – E.g. 2/6 samples failed 51 Number of Models 50 rapid cycle when the spec requires 5/6 to pass 40 – Marginal failure triggers elective retesting. 30 27 20 16 12 10 0 Marginally Failed Failed One Test Failed Two Tests Failed Three Tests Failed Four Tests

Summary of failures by test & batch • All other tests include • Start time • Power factor • Efficacy • CRI • ETLOR • Very low failure rates were observed for these tests

Interim Life Failures # of models # Models Tested Passed Marginal Failure Full Failure All Models 424 363 14 47 Bare Spiral 258 226 10 22 Bare Specialty 31 27 1 3 Covered 135 110 3 22 The interim life test looks at how many units are operational at 40% of the lamp’s rated lifetime claim. Note 1 unit failure is considered a pass and 2 unit failures is a marginal failure which allows for elective retesting.

Interim Life Failure Results • Of the 61 models that failed interim life 27 fully failed only this test – 9 failed interim life and marginally failed another test • We’ve had sample sets with 0 surviving lamps – (0 out of 20 in batch 4) • 20 models had 50% or less of their samples survive • 12 models had 25% or less of their samples survive
